  1. The answer is 3.
    Since the number of communication channels in an n person
    team is n(n-1)/2, we get the following communication
    channels for the given size of the team:
    3 people = 3 channels
    5 people = 10 channels
    7 people = 21 channels
    9 people = 36 channels
    11 people = 55 channels
    As you can see, above a team size of 3, people have to
    communicate a lot more thus reducing their productivity.
    So, three is the optimal number.

  2. For optimal size of a project team..
    the % increase in staff size should be “Zero”
    reason:
    additional member directly proportional to increase in
    staff size..
